Dornfelder

Intersection of Helfensteiner × Heroldrebe

The mandrel fields is an early-ripening red grape. August Herold she received in 1955 as a new breed at the State College and Research Institute for Viticulture and fruit growing in the vineyard by crossing the varieties Helfensteiner and Heroldrebe. It is named after the Kameralverwalter Immanuel Dornfeld, founder of the school of viticulture. Plant Variety Protection and approval by the German Federal Office received 1979 and 1980 Small stocks are also known in Switzerland ( 20.3 acres, as of 2007, source: Federal Office for Agriculture BLW ). .

The variety was selected according to their color intensity and originally cultivated as a cover wine. You should give more color than other red varietals blending partner the resulting vinified wine. In recent times, the spike fields but was also increasingly expanded varietal and is now available in different quality levels. Commonly, the wine obtained from thorn fields is considered harmonious. Various awards, including wine tastings at the German Agricultural Society eV ( DLG), suggest that the spike fields, partly bears his reputation as just a simple red wine wrongly.

The mandrel fields is also suitable as a table grape.

Ampelographic varietal characteristics

In the ampelography the habit is described as follows:

  • The shoot tip is open. She is very hairy.
  • The large leaves are five-lobed and sinuate medium low. The petiole is closed and widely overlapping. The leaves are coarsely toothed. The leaf surface (also called lamina ) is colored dark green.
  • The cone- shaped clusters are large to very large and mitteldichtbeerig. The roundish berries are large and blue-black color. The berry is thick-.

The mandrel drives fields from mid-early and is therefore sensitive to any late spring frosts. Due to its medium good lignification its winter hardiness is not very pronounced.

The vines are not very demanding on the soil and provide good returns. Dornfelder is sensitive to frost, drought and fungal diseases such as downy mildew. Because of the thick grape skins and loose- cluster of thorn fields is hardly affected by raw rot. Due to the increasing demand for red wines in general and especially after intense color varieties the thorn fields in Germany has become a fashion places. The wine from dornfelder has a black red color development and a fruity flavor. The acid expression (→ acid (wine) ) is rather moderate, acid-sensitive consumers comes to meet. With the high dye content, a high tannin goes hand in hand. Due to its characteristics, it is also suitable for aging in oak barrels (barriques ). Increasingly dornfelder is vinified white as well and further processed as a still wine into sparkling wine. In short maceration occur (often sweet ) rosé wines. In the Palatinate the thorn fields will be expanded also to spring Red.

The yield of the thorn fields is very high. To produce good quality wines consistently yield restriction on the pruning (→ Training system ) is essential.

Dissemination

In 2007 8185 acres ( 8.0 % of German vineyards ) were planted with the grape arbor fields in Germany. In the year 2006 8231 hectares were planted after only 3765 hectares were collected in 1999. In 1972, the vineyard was only 124 hectares. Thus, it is after the Pinot Noir is the second most cultivated Rotweinrebe that is grown primarily in the Rheinhessen and Pfalz wine-growing regions. The tendency of the cultivated area is stagnant or slightly declining for five years.

The vineyards in Germany distributed in 2007 as follows among the various regions:

The mandrel fields as intersection partner in new breeds

Meanwhile, other breeds have emerged from the mandrel fields, of which especially Cabernet Dorio, a cross appears promising with the Gamay. Other breeds on the basis of the Dornfelder are Cabernet Dorsa, Monarch and Acolon.
